guide time not advancing

Hi, running version 2.51.8 of progtv and when I go to epg I have a list of 7-8 channels with time from 4 to 7 o'clock and when I try to scroll in guide past 7 o'clock the guide does not change like from 7 to 8 then 8 to 9 it stays fix at that time of day. I did put the update to 1 hour but when I click update I see like an arrow circle pop up but its not rolling or anything ans does nothing in guide. Thank-you for the help
